Description

Technical Field

[0001] This utility model belongs to the field of timer technology, and in particular relates to a single-axis timer without an immersion function. Background Technology

[0002] With the progress of the times and the development of society, timers are being used more and more widely, such as in microwave ovens and washing machines. In particular, timers used in washing machines are divided into timers with soaking function and timers without soaking function. Existing timers without soaking function have eliminated the soaking function, so the timer only has a time cam and a buzzer cam, with a corresponding time lever, buzzer lever and corresponding contact spring. The internal structure is more complex, which increases the size and cost of the timer. It is also sometimes unstable, especially due to the design of the groove of the time cam and the time lever, which can be quite sudden at the moment of power failure. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a single-axis timer without an immersion function, which simplifies the structure and reduces costs.

[0004] The purpose of this utility model is achieved through the following technical solution: This single-axis timer without an immersion function includes a housing, a time cam, a time lever, and a controller for controlling the operation of the entire timer; the time cam and the time lever are respectively mounted in the housing via a rotating shaft; an arrow block is provided on one side of one end of the time lever, the arrow block abuts against the outer peripheral wall of the time cam; a push block is provided on the other side of one end of the time lever, the push block moves with the time cam and drives the time spring on the controller to contact or separate from the contact spring; a pull rod unit is provided below one end of the time lever, the pull rod unit moves with the time lever and drives the buzzer spring on the controller to contact or separate from the contact spring.

[0005] The beneficial effects of this utility model are as follows: Compared with the prior art, the buzzer lever and the time lever are integrated into one unit, and the buzzer cam is removed. By setting a push block and a pull rod unit on the time lever and cooperating with the time spring, contact spring and buzzer spring of the controller, the operation of the time cam enables the time lever to realize both the control of the power-on function and the buzzer function of the entire controller. It has the advantages of simplified structure and reduced cost.

[0006] Preferably, the controller is mounted on the housing, and the controller is provided with a time spring, an electric shock spring and a buzzer spring in sequence, and the time spring, the electric shock spring and the buzzer spring are distributed in the same plane; through the above structure, the three springs provided by the controller can be effectively controlled by the time lever.

[0007] Preferably, the controller is located on one side of the time lever, and the time spring, the electric shock spring, and the buzzer spring are sequentially located between the push block and the pull rod unit of the time lever; with the above structure, the push block and the pull rod unit of the time lever can realize the opening and closing control between the time spring, the buzzer spring, and the electric shock spring of the controller.

[0008] Preferably, the arrow block and push block of the time lever are distributed on the same plane and are flush with the time spring, electric shock spring and buzzer spring of the controller; the pull rod unit is located below the time spring, electric shock spring and buzzer spring of the controller; through the spatial layout of the time lever, the opening and closing control between the time spring, buzzer spring and electric shock spring of the controller can be realized by swinging the plane of the time lever back and forth.

[0009] Preferably, the pull rod unit includes a pull rod and a connecting block. The pull rod is fixed above the connecting block, and the connecting block is fixed below the end face of one end of the time lever. The pull rod is located on the side of the buzzer spring. By setting the connecting block, the pull rod can effectively contact and separate from the buzzer spring through the back-and-forth swing of the time lever.

[0010] Preferably, one side of the groove of the time cam is an arc-shaped surface, and the end of the arrow block of the time lever is an arc-shaped surface; this makes the sliding process smoother when the arrow block slides into the groove, so that the contact between the pull rod and the buzzer spring is not sudden, and the stability is better.

[0014] The present invention will now be described in detail with reference to the accompanying drawings: as shown in the drawings Figure 1 , 2 As shown, this utility model includes a housing 1, a time cam 2, a time lever 3, and a controller 4 for controlling the operation of the entire timer. The time cam 2 and the time lever 3 are respectively installed in the housing 1 via a rotating shaft. One side of one end of the time lever 3 is provided with an arrow block 31, which abuts against the outer peripheral wall of the time cam 2. The other side of one end of the time lever 3 is provided with a push block 32, which moves with the time cam 2 and causes the time spring 41 on the controller 4 to contact or separate from the electric contact spring 42. A pull rod unit 5 is provided below one end of the time lever 3, which moves with the time lever 3 and causes the buzzer spring 43 on the controller 4 to contact or separate from the electric contact spring 42.

[0015] The controller 4 is mounted on the housing 1, and the controller 4 is provided with a time spring 41, an electric shock spring 42 and a buzzer spring 43 in sequence, and the time spring 41, the electric shock spring 42 and the buzzer spring 43 are distributed in the same plane.

[0016] The controller 4 is located on one side of the time lever 3, and the time spring 41, the electric shock spring 42 and the buzzer spring 43 are located between the push block 31 and the pull rod unit 5 of the time lever 3 in sequence.

[0017] The arrow block 31 and push block 32 of the time lever 3 are distributed on the same plane and are flush with the time spring 41, electric shock spring 42 and buzzer spring 43 of the controller 4; the pull rod unit 5 is located below the time spring 41, electric shock spring 42 and buzzer spring 43 of the controller 4.

[0018] The lever unit 5 includes a lever 51 and a connecting block 52. The lever 51 is fixed above the connecting block 52, and the connecting block 52 is fixed below the end face of one end of the time lever 3. The lever 51 is located on the side of the buzzer spring 43. The lever 51, the connecting block 52 and the time lever 3 are integrally injection molded.

[0019] The groove 21 of the time cam 2 has an arc-shaped surface 22 on one side, and the end of the arrow block 31 of the time lever 3 has an arc-shaped surface 33.

[0020] The working principle of this utility model is as follows: When the timer is working, the arrow block 31 of the time lever 3 abuts against the outer peripheral wall of the time cam 2. At this time, the push block 32 of the time lever 3 pushes the time spring 41 to contact the contact spring 42, realizing the electrical conduction of the timer, that is, normal timing operation; when the arrow block 31 of the time lever 3 abuts against the groove 21 of the time cam 2, the push block 32 of the time lever 3 resets, the time spring 41 separates from the contact spring 42, and the timer is not energized. At this time, the pull rod 51 of the time lever 3 pushes the buzzer spring 43 to contact the contact spring 42, realizing the buzzer function of the timer.

[0021] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
